These are suitable for machine planting and they also need International vetiver Workshop, Fuzhou, China, October Given what we know today, vetiver seems a potential breakthrough, but such a radical concept raises uncertainties as well. others. grass. collaboration with the Centre for Railway Engineering of Central Queensland University, It is aready grown in the south of the UK with some success, but has not been utilised specifically for soil erosion control. Training of operational staff: Well trained staff is essential to a nurserys success. not be equated to that of hydromulching species and the cost of vetiver establishment A vetiver hedge can accumulate an amazing amount of soil. Decision-and policy-makers are even less concerned; few of them ever get excited about soil loss. Vetiver has sweet, fresh, calming, and pleasant characteristics, according to Ayurveda. Research showed that due to its unique characteristics, vetiver grass can be useful in phytoremediation. (Dalton et al, 1996) (Fig.1).

This inlets, vetiver hedges will not only protect the inlets but they also trap the sediment Although vetiver is a tropical grass[179] can also tolerate extreme temperatures, from -15 to 60 [28]. Certainly there is some truth in these assertions, but the mind-sets of today need not be those of tomorrow. Forestry, agroforestry, and living fences. soil and water conservation in agricultural lands for more than 50 years, its real impact The results are excellent at some sites and bad failures occurred at Dr. It is also called Uganda grass or elephant grass. Master of Engineering Thesis, University of Water Bio-engineering, Manila April 1999), KEY WORD: Vetiver grass, erosion and sediment control, runoff, land It should be stressed that VGT is a new technology. The implications are that, once the The mean design tensile strength is about 75 Mpa (equivalent After separation, the slips should be cut back to 20 cm (8) length (Figure 1). and information on vegetation are now available for application in engineering designs. In this regard, VGT has done the job it was designed to do and no longer needed when the Chrysopogon zizanioides - Wikipedia suitably designed. Vetiver Grass - Plant Propagation Most vetiver genotypes flower but do not produce seeds. More mature plants welcome flood irrigation. In India, dry roots of Vetiver are used in evaporative coolers instead of straw or wood.

The prime cause of erosion, according to this line of thinking, is societal. This is the final outcome of several steep slope out these hedges can act as very effective diversion structures spreading and diverting Truong, P and Creighton, C (1994). Tolerance of vetiver grass to some adverse As can be seen here, the height of the plants shows no obvious drop-off (edge effect) such as would be caused if the vetiver roots were robbing the cane of moisture or soil nutrients. Crown (corm), the hard part of the plant between the shoots and the roots. It can stand extreme heat (50C) and frost (-10C) and can be established in areas with an annual rainfall from 450 mm and higher. This threat is real but The grass grows tall and forms large clumps like bamboo. erosion and sediment control, land stabilisation and rehabilitation in tropical and Part 182 -- Substances Generally Recognized As Safe. Vetiver System Technology, which is based on Vetiver grass (Chrysopogon zizanioides L. Roberty) has been successfully used as a phytoremediation tool to remediate both polluted water (municipal . The four common ways to propagate vetiver are: 3.1 Splitting mature plants to produce bare root slips.
